This structure is incorrect. There should not be a double bond to the extracyclic amino group, but rather to the N in the ring (unless we want a bizarre resonance structure, but in that case we would need charges on the nitrogens).

I've removed the structure because, as I pointed out eight months ago, it is incorrect. Josh Cherry 14:09, 27 Jun 2004 (UTC)
- So, I assume that you'll be uploading a corrected image, real soon now? ;-) Lexor|Talk 23:51, 27 Jun 2004 (UTC)
- I agree with Josh. In my opinion, it is better to have no diagram than an incorrect diagram. Axl 18:58, 14 Dec 2004 (UTC)
Am I just being stupid, or is there no double bond attached to the extracylic amino group (I hope you're refering to the amino group on top of the six-membered—and aromatic, probably—ring?)? In any case, this current picture on the actual article and here on the talk page is consistent with what is in my textbook. Kr5t 02:13, 21 May 2006 (UTC)
Is this a real vitamin or not? I assume it's not: It's not listed on the vitamin page, and that page is quite explicit that there are only thirteen recognized (human) vitamins. But this page is also listed under category:vitamins.
It was considered one, once upon a time, but it turns out it isn't. Kr5t 02:14, 21 May 2006 (UTC)

[edit] Diagram/content
Well, the diagram is wrong. I dont know what the right one looks like, but this doesn't have H5. Also, I think it's important to include other common biological molecues that have Adenine in them. This includes, but is not limited to NAD, NADH... yeah. Can't think of anymore off the top of my head but it's a start.
- What's wrong with the structure? You mean that it doesn't have five hydrogens? It does. Two of them are implicit, according to the well established conventions for drawing structures (each of the two carbon atoms that would otherwise form only three bonds has a hydrogen substituent that's not explicitly shown).
- There are tons of biochemicals that contain an adenine moiety. I don't think we should show all of their structures here. Josh Cherry 01:19, 11 Feb 2005 (UTC)
Wow, you're totally right. I don't know how I missed that, the structure is right. As to the adenine-containing biochemicals, I think it is important to at least mention some of these and link to sites about those chemicals. DavidMendoza 23:33, 20 Feb 2005 (UTC)
Just a side, note, it does have five hydrogens, three of which are implicit, not two. And by the way, if you truly think we should list all the adenine-containing compounds (including activated intermediates and nicotinamide compounds?) a category would probably be more appropriate.

[edit] Part in article was wrong
In the article, it said that Adenine could form a base pair with thymine, but it also forms a base pair with uracil. Dogmanice 18:45, 19 March 2006 (UTC)
That's wrong...how? It can form a base pair with thymine, right? Besides (I don't know about what it looked like in your version) but right now, it's 100% correct. It's base pair in DNA is thymine and it's base pair in RNA is uracil.Kr5t 02:18, 21 May 2006 (UTC)
[edit] Tautomers
The diagram of adenine to the left of the text appears to inconsistent with that which appears on the right of the text (in the box with the SMILES and CAS number and other info). I recognize it as tautomers (correctly, I hope), but shouldn't we make a note of it? I hadn't even heard (read) of tautomers until earlier today, when I was studying SMILES.
